Abstract

Rolling process is one of the oldest metal forming processes and hot rolling has been considered for easy metal forming. Rollers used in hot rolling are very important due to the sensitivity of plate production. Therefore, the study of the amount of heat transferred to them during the rolling process, in addition to being crucial to the quality of the final product, also includes the cost of producing a roller and also cladding a portion of the cost of production. In this project, work rollers are simulated using a real rolling program belonging to Mobarakeh Steel Co. of Isfahan and also with the help of the powerful ABAQUS software. And after solving the heat transfer equations and applying the same realistic boundary conditions. The thermal contour and diagrams of roller average temperature has been plotted in normal conditions and by comparison with actual conditions, modeling accuracy has been investigated. In the next section, with the variations in the main rolling parameters such as rolling speed, coefficient of friction and reducing the thickness of the plate, the roller average temperature at various depths and the rolling forces are also considered. The reason of the increase or decrease of temperature in each section has been reviewed.
